The dependency list for this bug entry shows bug that we would like to fix for the next 2.7.x release. As fixes land on master, get tested, and get cherry-picked to the 2.7 branch, we will make new 2.7.x releases.
Please feel free to add bugs to this list if they are major bugs and you know of someone who's planning to cook up a fix.

I'm closing this since now that we've released 2.8.0 we're less likely to continue doing 2.7.x releases.
Meanwhile, of the 4 bugs that remain listed here, there's little to do on the 2.7 branch:
#17638 Closed without any specific commit we can point to that fixed the bug
#19304 Fixed in the kernel
#19578 A UMS modesetting fix (perhaps still a candidate for cherry-picking)
#21254 Already cherry-picked and in 2.7.1
So I'll remove the three from the dependency list and close this bug for now.
